Subterranean Microhabitat Dependent Intra Versus Extracellular Enzyme Secretion Capabilities of Deinococcus radiodurans

摘要

Deinococcus radioduransDeinococcus radioduransDeinococcus radioduransis one of the most yet discovered extremophilicmicrobe, the isolation of which from the various habitats of Kotumsar caveis always a matterof enticement to discover its ecological economics. In thepresentwork we studied the intraversusextracellularalkaline proteaseandglucose isomerase secretion capabilities of ;KCB21, KCB50, KCB93 isolated from three distinct subterranean niches ofKotumsar cave. The selected niches/zones were the entrance zone,transient zone and the deep inner zone from where the soil sediments werecollected to isolate the bacterial strains. The results revealed highextracellular alkaline protease activity from thestrain which was isolated from the deeper zones of the cave, whereas nosuchphenomenonwasrevealed forglucose isomerase. Thepossiblereasonfortheobtained results has beendiscussed.
